Weird as it looks, AMD released the new 16.11.2 driver just a day after releasing the .1 version. The .2 version driver increases AMD Shader cache storage limit. According to its release notes, the updated shader cache limit allows more shaders for extremely demanding games. There are no other optimizations.

The list of known issues for the 16.11.2 driver are as follows:

A few game titles may fail to launch, experience performance issues or crash if the third party application “Raptr” has its game overlay enabled. A workaround is to disable the overlay if this is experienced.

DOTA2 may experience a crash when launched using the Vulkan API on some Graphics Core Next products.
